Ravencoin fell 20.4% over 20 hours after a critical consensus vulnerability let invalid blocks slip past vulnerable nodes, pushing the network toward a rollback of roughly three days of transactions that its own developers didn't choose and couldn't stop.
The first invalid block appeared at height 4,487,776 on August 7 at 15:44:01 UTC. Ravencoin's official network notice confirmed the flaw caused invalid blocks to be accepted by vulnerable nodes and designated block 4,487,775 as the last confirmed-safe point, warning that any transaction confirmed after it should be treated as at risk. RVN's market cap has been cut to roughly $46 million, extending a slide that has now erased about half the token's value since late May.
Two Mining Pools, Not the Core Team, Are Calling the Shots
What makes this incident unusual is who is actually fixing it. 2Miners and RavenMiner, which together control the majority of Ravencoin's hash power, are mining an alternative chain that excludes every block built on the exploited branch from height 4,487,776 onward. 2Miners shipped its own emergency patch, version 4.6.1.1-hf1, that rejects forged blocks and locks in a checkpoint at block 4,487,775 — meaning the recovery path is being dictated by pool operators rather than the protocol's core developers.
A Ravencoin developer asked the pools to adopt a more recent recovery point to limit disruption for exchanges and users, but that request was declined. The project has been careful to note its warning shouldn't be read as an endorsement of any particular rollback plan, leaving the pools' three-day reorg as the de facto outcome rather than a team-sanctioned fix.
Exchanges Move to Contain the Fallout
Upbit in South Korea and Bitvavo in the Netherlands have already suspended RVN deposits and withdrawals, and developers have urged other venues to do the same until the chain state stabilizes. It's a now-familiar playbook: Ethereum Classic suffered a similar pattern in 2020, when a 3,693-block reorg tied to a 51% attack let an attacker double-spend 807,260 ETC, worth roughly $5.6 million at the time, prompting exchanges including Binance and Poloniex to freeze ETC transfers while the network sorted out which chain was canonical. Ravencoin's incident isn't attributed to a hostile 51% attack in the same sense, but the exchange response — freeze first, resolve later — mirrors what happened on ETC almost exactly.

For RVN holders, the practical upshot is that any transaction processed in the last several days could still be unwound once the pools' checkpointed chain overtakes the exploited branch, and the timeline for that depends on hash power the core team no longer fully controls.
